The wise put into practice

Learned Audience, what the ignorant merely talk about, wise men put into actual practice with their mind. There is also a class of foolish people who sit quietly and try to keep their mind blank. They refrain from thinking of anything and call themselves 'great'. On account of their heretical view we can hardly talk to them. ~ Hei Neng Sutra - Sixth Patriarch
